IR-LAGINE, WISCONSIN, A CORPORATION MOWER- Application filed October 9, 1931 Serial No. 567,847.

In the final assemblage of mowers it is essential that the sickle-bar shall be so adjusted in relation to the finger-guards through which its knives reciprocate as to be properly aligned therewith, but as commonly practiced with the various means at present in use, so

far as I am aware, when making such adjustments it becomes necessary to remove and then replace other parts of the mower, with considerable dirficulty and loss of time; and

it is my object, therefore, to provide simple means adapted to be readily manipulated for making such adjustments quickly and, accurately without disturbing any of the various elements of the mower, and to obviate the j-J my improvement is employed, the cutting mechanism being indicated as in proper adj ustment Fig. 2, a detail plan view indicating the cutting mechanisms out of alignment; Fig. 3, a detail section taken on the dotted a detail section on the line 4-4 in Fig. 3; and Fi s. 5 and 6 are perspective views, respectively, of a shim and a stop forming parts of my improvement.

In said drawing the numeral 5 indicates a :5) shoe support embodying a sleeve 6 in which a shaft 7 is mounted, in a well know manner, said support being lnn 'edly connected, at 8, to a shoe 9 of any ClGSlIQCl' construction and I I, arrangement, which shoe with a sickle-head 10-10, cutter-bar 11 and pitman guides 12 are secured by bolts is, as is common, so that said parts 9, 10, 11 and 12 constitute unitar 7 structure pivotally mounted on the shoe sup port to be swung vertically for purposes well known. As usual, a pitman 14 connected to the sickle-head 1O reciprocates the sickle-bar 15 carrying the knives 16 which cooperate with finger-guards 17 to cut crops, and as said parts with those illustrated in Fig. 1 may be of well known construction and arrangement itwill be unnecessary to describe them I specifically.

My improvement consists in the use of a sleeve, as 6, having an opening 20 therein, as clearly indicated in Fig. 4, registering with an opening 21 through shaft 7, into which latter opening a stop is driven comprisinga head 24 having an opening 25 therethrough, and a pin or shank 26by which the shaft and stop are locked against moving, while the sleeve may move longitudinally on the shaft.

In Fig. 1 the parts of the mower are'indicated as in normal adjusted relation after the mover has been assembled, in which .view it will be seen that I employ a bolt 28 parallel with the sleeve 6 and the passing through the head 24 and through shims 30, 30, at

each side of the head,- the shims being apertured, at 31, for the purpose, and preferably are of the shape of the ends of the head 24, and which shims and head take up any misadjustment which might exist between the sickle-bar and fingerguards to cause said elements to beout of alignment. Innormalpo ition the relation of the finger-guard 17 and one, of the cutting knives 16 is indicated by the dotted line passing centrally, through said parts, but when not properly 'adjusted'the knives may be positioned out of line with the finger-guards either at one-side or the other thereof, substantially as indicated by the center lines in Fig.2, upon which occurrence the adjustment may be readily-corrected by transferring one or both shims 30 from the lefthand side of the head, as seen when looking at Fig. 1, to the opposite side, and, as the case may be, driving one orboth home, when the I head and shims thus assembled maybe se cured by the bolt 28 as. shown. By thus driv ing the transferred shims between the shims 30 and the sleeve 6 .it will be seen that the shoe support, the shoe through its hinged con nection and pitman guides andccutter-bar, as

a unit, will be forced laterally along the sickle-head until the outer edge 9 of the wardly to thedesired position and the shims and head again secured by the bolt in the man I ner before described. 7 By my improvement simple means are provi e for readily a d positively aligning the sickle-bar and its I 'knives in relation to the finger-guards and that as the take-up means are in exposed position ready access thereto is permitted without the removal and replacement of other parts of the mower sary in common practice and therefore objectionable. I I

I claim as my invention:

1. In amower having a shoe support, a p shaft upon which said support is mounted,

a shoe connected to the support, reciprocating'cutting devices mounted upon the shoe,

means foractuating the devices, means for adjusting the support in relation to the cutting devices comprising a stop insertable through the support. and into the shaft said stop having shims at its sides, and means for detachably securing the stop and shims together. Y

2. In a mower adjustably in longitudinal relation to the shaft, a shoe connected to the support,a sickle-bar slidably mounted on the shoe, means for reciprocating said bar, means for securing the supportand shaft together, and means associated with the securing means for urging the support longitudinally on the shaft to adjust the sickle-bar.

3. In a mowe'r'having a shoe support, a shaft upon which said support is adjustably mounted, a shoe connected to thesupport, a sickle-bar slidably mounted on the shoe,

means for reciprocating the bar, means for adjusting the support on the shaft including a head having a pin extending therefrom adapted to be inserted in the support and shaft and wedging means insertable alongside'the head, and means for maintaining the head and wedg-ingmeans in assembled relation. A f

l. In a mower ineluding a shoe supporting sleeve having an aperture in its wall, a

shaft upon which the support is mounted and having an aperture therein registering with the sleeve aperture, means in'sertable in the apertures for securing the shaft and sleeve in non-rotatable relation, andmeans adapted which, as stated, is necesand the sleeve for adjusting the latter 1ongitudinally on the shaft. 7

'5. In a mower including a shoe supporting sleeve having an aperture in its wall, a shaft upon which the support is mounted and having an aperture registering with the sleeve aperture, and means insertable in the apertures for securing the shaft and sleeve in non-rotatable relation and also for limiting the longitudinal movement of the sleeve on on. V 1 v n testimony whereof I afiix my signature.
